' Application filed May-*3,

a citizen of the Unitedstates, residing at Portland, in thecountyjof'Multnomah, State of Oregon, haveJinve-nted certain new anduseful Improvements in Amalgamator Sup ports; and I do hereby declarethe following to be a full, clear, and exact description oftheinvention, such as will enable others skilledin the art, to which itappertains' to make and'us the same;

This invention relates .to .new and useful improvements 'in'amalgamators; and par ticularly to skids'or supports therefor.

justable soas to maintain the platform, or sluicesupporting means, in aperfectly level or'horizontal position with the result that the sluice,and 1 other mechanism supported .on 'the' platform, willbe dis-posed atthe proper angle for the successful operation thereof 1 Another objectis to provide novel and improvedmeans for adjusting the platformandskid'sthereof, and means for supporting" the weight'of the-platform,to relieve the adjusting means, while the device is operation.

A further object isfto provide novel and improved means for holding theplatform or bed, and the skids Y in positiom agalnst displacement,.while in" lowered'or "folded position. I

Other objects and advantages will be apparent from the followingdescription when taken, inconneetion with the accompany ing drawings:

In the drawings; v Y Figure 1 is a side'elevation of an amalgamatingmachine showing the improved bed and skids. I i 1 Figure 2 is an endelevation of the same. Figure 3 is a vertical transverse sectional viewon the line 33 of Figure in the direction of the arrows,

Referring particularly to'the accompanying drawings, there is shown astaging including the longitudinal parallel side sills 10,'-betweenwhich extend the transverse beams 11, on which are supported thesuperstructure 12, carrying the amalgamating sluices and screen cylinder13 and 14, ,re& spectively, and the englne platform 15. Mounted insuitable brackets 16, on the 1, look- 19 22. SerialIt'o. 557,918.

forward end of the staging, is a transverse shaft-17, and rockablyengaged with the ends offthe; shaftare the bearing brackets 18, whichare carried by the upper edges; of the forward portions of thQ'SklClS19. These skids 1 9 extendlon'gitudinally beneath the staging andareadapted to be swung..vertically' into different angles ffor'restingon slopes of various degrees, so that the stag ing will lie in ahorizontal plane; Ex tending from the' rear' endof "each of the sidesills 10 isaybearing bracket 20, through I which is verticallydisposed-an elevating p screw 21.] Secured 'to'the upper face of eachOne objectof the invention isto provide 7 skids of the character namedwhich are ad'- of' the brackets 20 .isqa housing 22 having openings .23in :its opposite sides through a plurality of openings 25, forthereception' ofa suitablebar tool, for thegpurposeof rotating the nutto;elevate "and lower the stage. The lower end; offeach scr'ew-"'2l-;is swivel'ed in a socket -bearingi"plate- :26,

mountedf'on the upperedge of i the rear "end portiono-f the skid 19.ThfiSylOy rotating thenut '24,;the rear 'endof the'staging can be raisedand lowered, as theconditio'n'fs and slope of the ground warrmtpTheskids'19 are connected, near their K for-ward and jrear ends, by meansof'ithecrossg beams27; IOn the outer sideface of. "the rear end of each.

of-zthe' skids thereis mountedyahook 2.

which is arrangedto b'e'engaged by any one of a series-of chain links29, carried by the staging," and whereby, when the stag ing has beenlowered onto the skids, the 7 skids will be held against undue movementvertically," and the staging] maintained against vertical movement.

When the staging has been elevated to the. proper level, in "accordance4 with the" slope of the'grade, on which the machine is being'used,theweight wouldbe sustained by the elevating screws 21. To obviate this, Tplace a block 30 on-each of the skids 19, and a block 31 beneath eachend of one or more of'the cross beams 11, and thenrdrive suitable wedges32'between the adjacent ends of the blocks, to support the weightof thestaging, and the mechanism carried thereby,

and thus relieve the threads ofthe screwsand nuts from injury; The upperends of the chains 29 have the 'nutandjscrew means 511,; for drawing thechains to move the skids and staging toward each other, for the purposeof firmly binding the wedge blocks 32 and the blocks and 31 together.

Centrally pivoted on the upper rear portion of the superstructure is atransverse rocker 33, and connected to the ends of this rocker, andextending downwardly and rearwardly from the machine, are the I-beams34, beneath which is secured the metal bottom plate 35. Properly securedto the upper face of this plate 35, and extending in parallel relationto each other, and in parallel relation with and between the bean'is 34,are the rails 36, bQtWQQll WlllCll the elevating bucket 37 is arrangedto slide. Tl is bucket 37 has connected thereto a cable 38 which passesupwardly over a pulley 39, mounted on the superstructure, and by meansof which the bucket is raised and lowered for the purpose of dumping theplacer gravel into the hopper 40, at the upper end of the cylinder 14:,from whence the gravel falls into the said cylinder.

The sidebeams 34 are pivotally connected to the ends of the rocker forvertical swinging movement, while the rocker is pivotally supported forhorizontal swinging movement, thus enabling the operator to move thebucket guideway into any vertical and horizontal position, within agiven distance or radius.

What is claimed is: I

1. A support for an. amalgamator comprising a staging, skids movablyconnected with the staging, means for elevating and lowering one end ofthe staging with relation to the skids,'me'ans for supporting the weightof the staging independently of the elevating means, and means fordrawing the staging and skids toward each other to bind the saidsupporting means.

2, A support for an amalgamator comprising a staging, skids Vmovablyconnected at rea one end to one end of the staging, elevating meansbetween the other ends of the staging and skids respectively, meansadjustable between the staging and the skids for supporting the stagingindependently of the elevating means, and means for drawing the stagingand skids toward each other to bind the said adjustable means.

. 3. A support for an amalgamator comprising a staging, skids disposedbeneath the staging and being pivotally connected at. one end to one endof the staging, elevating'and lowering screws operatively connected withthe other ends, ofthe staging and skids respeetively, wedging meansremovably engaged between the staging and skids intermediate the screwand pivots of the skids for supporting the weight of the stagingindependently of the screws, and flexible tensioning means between thestaging and skids for irictionally binding the wedging means.

4. A support for an amalgamator comprising a staging, skids pivotallyconnected to one end of the staging, elevating screws movably connectedto the skids, guides on the staging receiving the screws s-lidably therethrough, housing on the guides, nuts in the housings receiving thescrews threadedly therethrough, hooks on the sides of the skids, chainscarried by the staging and engageable with the hooks, blocks engagingthe staging and skids, wedges between the blocks for supporting thestaging independently of the screws, and tensioning means between thechains and staging for drawing the chains to move the staging and skidstoward each other for frictionally binding the wedges and blocks.

In testimony whereof, I a ture, in the presence of a witness.
